"procinfo" on Red Hat 7.1 is version "procinfo-17-10". It works fine with
the 2.2 kernel, but the 2.4 kernel changed the format of the disk
statistics in "/proc/stat". As a result, "procinfo" on Red Hat 7.1 doesn't
display disk statistics.
Reproducible: Always
Steps to Reproduce:
1. Install Red Hat 7.1 and "procinfo".
2. Type "procinfo -Dn10" in a terminal window.
3. Do some disk activity. You won't see any disk statistics.
4. Repeat the above steps on a 7.0 system with the 2.2 kernel and you will
see disk statistics.
